摘要
以某化工厂丙烯聚合关键设备——环管反应器为例,通过熟悉工艺流程,选取合适的关键变量,确定变量之间的影响关系,建立用于故障诊断的SDG模型。在与工厂工艺操作手册及仿真模型模拟分析校对该模型后,对该模型进行了故障诊断分析。实验结果表明,基于SDG模型的故障诊断能够准确地揭示故障传播路径。
Taking loop reactor in the propylene polymerization process as an example, the proper variables were selected and the relationship among them were confirmed to build a SDG model for fault diagnosis, then having it checked with operation manual and simulation model. Experimental result shows that the SDG-based fault diagnosis can reveal the fault path clearly and accurately.
